@coalakida I’m so sorry to hear your Glowforge is having to cool down at a lower temperature than before.

It looks like @ca_worth had a good idea of checking the air flow of your Glowforge.

To help troubleshoot your issue, could you post a few photos of your exhaust system? Specifically, please include pictures of the following:

  1. The exhaust fan from the inside of the unit. To capture this photo:

  2. Turn your Glowforge off

  3. Open the lid

  4. Using both hands, gently pull the printer arm towards you as shown below:

  5. Move your phone or camera inside the Glowforge on the left-hand side, past the metal rail, pointed away from you towards the exhaust hose, to capture a photo like the one below:

  6. A photo of where your exhaust hose attaches to the Glowforge, where your exhaust hose exits the room, and the path your exhaust hose takes from your Glowforge to the exterior vent or Compact Filter

  7. The exhaust connection on the back of your Glowforge, with the exhaust hose removed:

  8. Any area where you see smoke escaping from your Glowforge while printing

It’s been some time since we’ve heard from you @coalakida , would you let us know if you’re still experiencing trouble?
